7862a433e9 Clear the dmesg buffer to prevent rotating causes issues
This is a workaround for the current continuously failing test case

sys.kern.sonewconn_overflow.sonewconn_overflow_01

The side effect is the dmesg buffer got cleared and may effect other tests

tailing the log file like /var/log/debug.log

9c7bd4f198 crunchgen: fix MK_AUTO_OBJ logic after r364166
r364166 converted echo -n `/bin/pwd` to a raw pwd invocation, leaving a
trailing newline at the end of path.  This caused a later stat() of it to
erroneously fail and the fallback to MK_AUTO_OBJ=no logic proceeded as
unexpected.

Harry Schmalzbauer bissected the resulting build failure he experienced
(stable/12 host, -HEAD build) down to r365887. This change is mostly
unrelated, except it switches the build to bootstrapped crunchgen - clue!

I then bissected recent crunchgen changes going back a bit since we wouldn't
observe the failure immediately with -CURRENT in most configurations, which
landed me on r364166. After many intense head-scratching minutes and printf
debugging, I realized that the newline was the difference. This is where our
tale ends.

92e17803cd Enable iterating all sysctls, even ones with CTLFLAG_SKIP
Add an "nextnoskip" sysctl that allows for listing of sysctls intended to be
normally skipped for cost reasons.

This makes it so the names/descriptions of those sysctls can be discovered with
sysctl -aN/sysctl -ad/sysctl -at.

It also makes it so children are visited when a node flagged with CTLFLAG_SKIP
is explicitly requested.

The intended use case is to mark the root "kstat" node with CTLFLAG_SKIP so that
the extensive and expensive stats are skipped by default but may still be easily
obtained without having to know them all (which may not even be possible) and
request each one-by-one.

546f18f3da lualoader: improve the design of the brand-/logo- mechanism
In the previous world order, any brand/logo was forced to pull in the
drawer and call drawer.add{Brand,Logo} with the name their brand/logo is
taking and a table describing it.

In the new world order, these files just need to return a table that maps
out graphics types to a table of the exact same format as what was
previously being passed back into the drawer. The appeal here is not needing
to grab a reference back to the drawer module and having a cleaner
data-driven looking format for these. The format has been renamed to 'gfx-*'
prefixes and each one can provide a logo and a brand.

drawer.addBrand/drawer.addLogo will remain in place until FreeBSD 13, as
there's no overhead to them and it's not yet worth the break in
compatibility with any pre-existing brands and logos.

8073c947c7 ngctl: add -c (compact output) for the dot command
The output of "ngctl dot" is suitable for small netgraph networks. Even
moderate complex netgraph setups (about a dozen nodes) are hard to
understand from the .dot output, because each node and each hook are shown
as a full blown structure.

This patch allows to generate much more compact output and graphs by
omitting the extra structures for the individual hooks. Instead the names of
the hooks are labels to the edges.

0400be45e9 Add sig_intr(9).
It gives the answer would the thread sleep according to current state
of signals and suspensions.  Of course the answer is racy and allows
for false-negatives (no sleep when signal is delivered after process
lock is dropped).  Also the answer might change due to signal
rescheduling among threads in multi-threaded process.

Still it is the best approximation I can provide, to answering the
question was the thread interrupted.

0c82fb267b Refactor sleepq_catch_signals().
- Extract suspension check into sig_ast_checksusp() helper.
- Extract signal check and calculation of the interruption errno into
  sig_ast_needsigchk() helper.
The helpers are moved to kern_sig.c which is the proper place for
signal-related code.

Improve control flow in sleepq_catch_signals(), to handle ret == 0
(can sleep) and ret != 0 (interrupted) only once, by separating
checking code into sleepq_check_ast_sq_locked(), which return value is
interpreted at single location.
